Teflon tape
What is the difference between yellow (for gas applications) and white Teflon tape?
Forum Discussion
Looked it up.
White- single density, should only be used on NPT threads up to 3/8 inch in diameter.
•Yellow – double density, often labeled as “gas tape”
•Red of Pink – triple density, required on all joints 1/2? or larger.
•Green – oil Free PTFE tape, required for use on all lines carrying oxygen (i.e. – medical oxygen or welding oxygen lines).
